Question

. Find the mean, median and the mode of the following frequency distribution. Class 0-10 10-20 20-30 30-40 40-50 50-60 60-70 frequency 4 5 7 10 12 8 4

​

Answer 1

Answer: Mean =7.14

Median =7

Mode = 4

Step-by-step explanation:

Mean = sum of observation

no. of observation

=4+4+5+7+8+10+12

7

50

7

=7.14

Median = n+1

2

n= no. of observations

7+1

2. n^th term

4 th term

arrange in ascending order

4,4,5,7,8,10,12

Median =7

Mode is the number occurring most of the times of all observations

Mode =4
